The largest professional-networking website, LinkedIn has doubled to $94.25 on the first day of trading after a successful Initial Public Offering (IPO).

The 109% rise is best performance recorded by company recorded in months and is favorable news for the IT industry. The IPO only included 7.8 million, or 10%, of the total shares.

The successful response has shown that there is a lot of investor interest for social networks. LinkedIn’s IPO could open the flood gates for other big social-networking companies to go public. Investors are eagerly waiting for similar moves from Facebook and Twitter.

Analysts say that even as a 109% rise is not matched to the figures from the time of dot com growth, it is clearly a very positive sign for the internet companies.
